On the other hand, the existing first patent document that traditional aircraft skin automation cutting equipment such as background technique is enumerated
In record could be aware that conventional airplane covering automates three rail wheels of cutting equipment in isosceles to equilateral triangle form
Gripper rail, while the cutter device 2 and its cut place are suspended from the top among two driven wheels 12, such form on the one hand by
In cutter device 2 apart from the driving wheel 14 apart from too far, in addition track is not wide, then it can be top-heavy in cutting, thus cause
Track twist and warping are rocked so as to cause the cutter device 2 generation, are unfavorable for cutting stability.
And on the other hand since the axle center of the driving wheel 14 and the cutter device 2 is close to being located on a middle line, simultaneously should
The torque revolving speed of cutter device 2 and the revolving speed and torque of the driven driving wheel 14 of driver 15 are had nothing in common with each other, therefore are turned at the same time
The rotary force of the two and active force can be made to be on logical same middle line and generate interference and shaking each other when dynamic operation, thus
The surface curvature consistency for reducing the cutting track and covering when aircraft skin automation cutting equipment operation, reduces cutting essence
Degree.

Show that there is curve combined area F thereon, and in order to be adapted to these curves to the greatest extent, therefore precision should not be limited with the gear teeth, together
Even if when gear teeth setting the hidden danger that is interrupted of carefully also having exist very much, therefore do not set the knot of the gear teeth in the present embodiment with track 5
Structure, the active wheel construction that Lai Peihe is toothed around, even if so that being more bent at the F of curve combined area, so that driving wheel is slight
It skids, but is promoted by the frictional force of the gear teeth on the driving wheel 14, can also be passed through slowly, so as to improve aircraft skin
Automate cutting equipment geometric locus fitness.
And under another preferred embodiment, those skilled in the art as shown in Figure 3 can also select according to actual processing scene
The tooth socket for being equipped on the occlusal surface of track 5 and being adapted to 14 gear teeth of driving wheel is selected, so that aircraft skin automation be avoided to cut
Equipment is cut to skid on the rail 5.
